This blog post is not true and not fair. Airbnb specifies that there must be textual disclosure of any cameras, and there is a section on the listing page that shows them.
It's also very rare for a security system to include indoor cameras. My own uses motion detectors to provide information about climate control and lighting needs, but absolutely no interior cameras.
It's not clear to me that the object in the picture is a camera. If it is, I do think the host should rethink having cameras in a bedroom, but if that's what it takes for him/her to feel comfortable renting out the home, then as long as it's disclosed clearly, then it's OK.
